Question

what is photophosphorylation ? describe cyclic photophosphorylation​

Answer 1

Answer:

Cyclic Photophosphorylation is the process in which organisms (like prokaryotes), just accomplish the conversion of ADP to ATP for immediate energy for the cells. This type of photophosphorylation usually occurs in the thylakoid membrane.

Answer 2

Answer:

Cyclic Photophosphorylation happens with the help of photosynthesis, a process of producing carbohydrates by green plants using carbon dioxide and water in the presence of sunlight. The two-step process comprises:

The light reaction which takes place in the grana of the chloroplast where light energy gets converted to chemical energy as ATP and NADPH. In this reaction, the addition of phosphate in the presence of light or the synthesizing of ATP by cells is known as photophosphorylation.

While in the dark reaction, the energy produced previously in the light reaction is utilized to fix carbon dioxide to carbohydrates. This takes place in the stroma of the chloroplast
